The first and second barriers are configured to modify the cross-sectional areas of the openings when actuated. The actuator is configured to actuate the barriers, and the controller is configured to direct the actuator to actuate the barriers so that the cross-sectional area of the first opening is larger than the cross-sectional area of the second opening so that a pressure at the inlet is greater than a pressure at the outlet.

An apparatus for manufacturing a display device include: a tray on which a window is seated, a belt on which the tray is seated, where the tray is moved by the belt, a first pulley which rotatably supports the belt, a second pulley arranged to be spaced apart from the first pulley, where the second pulley rotatably supports the belt, and a driving portion connected to the second pulley, where the driving portion rotates the second pulley.

A device for removing a defective electronic component from a circuit board includes a vacuum suction nozzle, a laser beam emitter and an infrared temperature sensor. The vacuum suction nozzle has a suction opening at which suction is generated. The suction opening is dimensioned to be larger than the defective electronic component. The laser beam emitter is oriented so as to emit a laser beam out the suction opening towards the electronic component on the circuit board. The temperature sensor measures the temperature of the electronic component based on infrared radiation emitted from around the electronic component. A method for removing the defective electronic component from the circuit board includes positioning the suction opening over the electronic component and directing the laser beam through the suction opening and onto the electronic component so as to heat and detach the electronic component, which is then sucked into the vacuum suction nozzle.

There is provided a method for producing a metallic workpiece in layers by additive manufacturing, metallurgical layers of the workpiece being produced by providing a metal material in a manufacturing chamber for each metallurgical layer and applying a laser beam to the metal material, and providing a gas atmosphere in the manufacturing chamber during the application of the laser beam to the layers of the metal material, wherein a part of the gas atmosphere is drawn off from the manufacturing chamber as a gas stream, at least one parameter of the gas stream and/or the gas atmosphere being determined and being compared with a desired value. Depending on the comparison of the parameter with the desired value, the gas stream is fed back to the manufacturing chamber and a process gas is supplied to the manufacturing chamber.

A laser processing apparatus includes: a work support portion which supports the work and forms a closed space between the work and the work support portion; pads which are movable upward and downward inside the closed space and include upper surfaces respectively coming into contact with regions obtained by dividing a processing object region having the through-holes formed in the work to surround the region of the work over one circle when the pads move upward; a drive unit which drives the pads to move forward and backward between a state in which the pad is in contact with the work and a state in which the pad is separated from the work; a gas supply unit which supplies a gas into the closed space; and clamps which contact the work supported by the work support portion on inner circumferential surfaces and outer circumferential surfaces from above over one circle.

A shielding gas nozzle for metal forming includes a wire feed line being a path to feed a wire at an inclination angle θ, a first gas ejection hole to jet a shielding gas at an angle equal to or less than the inclination angle θ, and a second gas ejection hole to jet the shielding gas in a direction different from that of the first gas ejection hole. The first gas ejection hole jets the shielding gas toward an intersection along a direction in which the absolute value of the angle to the wire feed direction is less than 90 degrees, and the second gas ejection hole jets the shielding gas toward the intersection along a direction in which the absolute value of the angle to the wire feed direction when viewed in the direction perpendicular to the base material surface is greater than 90 degrees.
